I have been a gold bug for the past few years. I became one because I could see that money printing by central banks was fast devaluing the fiat currencies and I wanted to preserve what little I had.
Gold has been the go to investment at such times primarily because it is scarce and unlike Fiat, it cannot be reproduced ad nauseam.
Blockchain technology and specifically Bitcoin are beneficial because of true scarcity (21 million BTC) which trumps gold because we are still mining gold.
Because it is decentralised that will hopefully remove the ominous presence of central bank influence. But you can bet your bottom BTC that they will go down fighting hard against that.
The technology is full of promise for many different applications and fills me with optimism.
Benefits of a public blockchain like Bitcoin is; immutability in the form of a ledger known as the blockchain, decentralisation in the form of nodes, transparency open ledger aka the blockchain.
Benefits of Blockchain technology:
- It is an immutable ledger
- decentralized
- transparent
- accessible/usable for everyone with internet access
- TRUTH
Blockchain technology allows open and ethically transparent commercial activity around the world, it is immutable, decentralised, transparent, traceable, and accessible/usable for everyone with internet access AKA a necessity to support a better and more fair world.
- Cost efficient
- Transparent
- Globally accessible by anyone
- Decentralized
- Secure
- Higher speed transactions
- No authority, eliminates middlemen
Blockchain technology is incorruptible, immutable. Corruption is the largest problem facing society.
The second is inequality of opportunity. Opportunity in this age, is measured in fiat currency which is controlled by the few to enslave the many. Blockchain technology in the hands of all free prosperous people, will keep all of us, free and prosperous.
Glad to see a new financial system in development that delivers more freedom and less corrupt interference of central authorities! While it gives more financial independence and privacy Iām very interested in this technology
Blockchain technology allows a fair way to transact and transfer money. I believe It will eventually help to redistribute and decentralize wealth around the world
I see it as a future. Idk how, but it will happen. Today Iād question thoroughly the key concepts by which blockchain functions to find ways to improve and optimize the eco system to support scaling which will allow to replace traditional centralized mass data processors.
Iām confused about the concept of having all the transaction history on each of the nodes? Is that how it works? How much data should everyone hold? How this will be salable when more dapps will be in use? Wonāt we hit the storage crisis where nodes will just not be able to keep it all?
Yes, all transactions are permanently stored and I wouldnāt worry about it. Storage these days is so cheap its not really an issue imo 
Benefits of using Blockchain is transparency, verification and it transcends boundaries without cost.
Main advantages includes:
- Using blockchain allows verification without involvement of middle-man;
- Offers a high level of security by making use of cryptography;
- Transactions are transparant and can be verified.
With blockchain we dont have to trust, we can just VERIFY!
i didnāt really get how hash function is a one-way function
if there is something to do with random number we canāt have the same output whit the same input and if not, the algorithm can be reversible.
itās kind of confusing can any body help me with that please?
In a Hash function, the input undergoes complex mathematical operations and provides always the same result from the same input. Itās impossable to calculate the input from the output!
For example,
Take a simple mathematical operation like addition. The addition takes 2 inputs and produces 1 output (the sum of the two inputs). If you know the 2 inputs, the output is easy to calculate - and thereās only one answer.
321 + 607 = 928
But if you only know the output, how do you know what the two inputs are?
Thank you 
really helpful.
transparent, open and decentralised
#1 Blockchain can be government less money.
#2 Blockchain has a myriad of efficiency improvement cases.
From the first introduction I completed, I fell in love with such a surprising topic: the āBitcoin central bankā perfect monetary policy where a reading exposed the transaction costs of BTC:
- Storage - free & 100%
- Transportation: cryptographic
- Fiduciary media: impossible
- Record keeping: automatic
- Counterfeiting: impossible
- Issuance: algorithm
- Payment clearing: cheap & distributed
- Scarcity: fixed - 21mio BTC
- Authentication: built-in
Mind BLOWING in continual mode, first of all, because I see TRUST built-in. How many are struggling on this planet to trust anyone, anything, any offer?
How many of you are feeling this superpower of trust built-in at the conception of bitcoin?
I am in love. That is it.
